J. Biochem. 227:19-26(1995). CC -!- FUNCTION: Acts by replacing the acid subunit in the crotoxin CC complex, inhibiting the PA2 activity of the basic subunit. CNF is CC able to inhibit basic and acidic PA2 from L.m.muta and CC B.jararacussu, even more efficiently. CC -!- SUBUNIT: Homomer composed of six to eight subunits. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- TISSUE SPECIFICITY: Expressed by the liver and secreted in plasma. CC -!- SIMILARITY: Belongs to the CNF-like-inhibitor family.
